From 3.13.0 until 4.6.2, the server-island renderer serializes raw useHeadSafe entry input into the island response without preserving the safe-input marker, and NuxtIsland later inserts that input into the page head as an ordinary entry. An application that passes attacker-controlled data to useHeadSafe in a .server.vue component or page, or in a component rendered through NuxtIsland, can therefore render values normally removed by the allowlist, including event-handler attributes or executable script content, resulting in stored cross-site scripting in the application origin. This issue is fixed in version 4.6.2 .","state":0,"publishedAt":"2026-10-21T18:17:26.26+00:00","modifiedAt":"2026-10-28T18:17:10.55+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/nuxt/nuxt/commit/493565e99451a0f52330b1f6b979254a4a39e5d0","https://github.com/nuxt/nuxt/releases/tag/v4.6.2","https://github.com/nuxt/nuxt/security/advisories/GHSA-xfq5-w38q-pc2x"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114133","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-10-21T18:17:26.260","lastModified":"2026-10-28T18:17:10.550"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
